Fitness needs attention:
First, avoid "working" at high temperature.
Keep a short period of low exercise in summer, and let your body adapt to the hot weather slowly. Especially when the sun is strong from noon to 2 pm, try to avoid outdoor sports, because ultraviolet rays are particularly strong during this time, which will burn the skin and even stimulate the retina and meninges.
Second, choose clothes that absorb sweat.
When you exercise in summer, the temperature and humidity are very high. You must wear a sweat-absorbent cotton shirt, not a tight sportswear. If the moisture can't be discharged, it will put a lot of pressure on the heart. And you can't hang clothes with your own body. It is best to prepare a set of dry clothes, especially a coat, and put on wet clothes immediately after exercise, otherwise it will easily lead to rheumatism or arthritis.
Third, replenish water in advance.
The temperature is very high in summer, and a lot of exercise makes the water in the body lose faster. Therefore, it is recommended to drink 800 ml of water half an hour before exercise. If outdoor exercise lasts more than 30 minutes, be sure to bring a bottle of water, preferably supplemented with salt.
Fourth, a reasonable diet.
Eat staple food or fruit an hour before exercise. This is to prevent the intake of calories is too low, leading to poor physical strength.
5. Don't drink too much water.
If you drink plenty of water after exercise, it will increase the burden on the blood circulation system, digestive system, and especially the heart, making you more tired. The result of drinking plenty of water will only be more sweating, further loss of salt, causing convulsions and cramps. It is recommended to drink several times, only a few mouthfuls at a time. In addition, don't eat too many cold drinks after exercise, otherwise your body will suddenly lose the balance of internal cold and external heat, causing stomach discomfort.
